Embodiment 1

[0028] Embodiment 1. the preparation method that contains the plant growth promoter of chitosan

[0029] The chitosan-containing plant growth promoter whose chitin is decomposed is prepared through the following steps.

[0030] (a) prepare 25kg of grain (malt powder for animal feed as the main raw material), absorb the step of 200g of chitin powder;

[0031] (b) the step of adding 30ml of microbial culture solution (Rhizopus oligosporus (a kind of white cotton wool mold) and 3000ml of water (containing minerals)) to the above-mentioned cereals on which chitin powder has been adsorbed;

[0032] (c) adding the composition prepared in the above step (b) into a blender to mix it;

[0033] (d) the step of putting the composition prepared in the above step (c) into a well-ventilated container and fermenting it for 4 days;

[0034] (e) a step of drying the fermented product of the above step (d);

[0035] (f) A step of pulverizing the dried fermented product with a mesh size of 25...

Embodiment 2

[0036] Embodiment 2. utilizes in the lettuce that contains the plant growth promoter of chitosan, confirms that chitosan

[0037] 1. Method

[0038] Sprinkle the chitosan-containing microbial preparation into the soil and mix well, and perform foliar fertilization or perfusion at intervals of 15 days to 20 days.

[0039] 2. Results

[0040] As a result of an experiment commissioned by the Korea Food Research Institute, 0.06 mg / g of chitosan was detected (Figure 1). The above results show that chitosan can be contained in lettuce which cannot synthesize chitosan by the method of the present invention.

Embodiment 3

[0041] Example 3. Confirmation of the effect of growth promoter (power Green-F) containing chitosan

[0042] 1) Purpose of the experiment

[0043] This study is to confirm the effect of power Green-F prepared according to Example 1 on the growth of crops.

[0044] 2) Experimental method

[0045] 1) Publicized crops: leafy vegetables - radishes ([species])

[0046]2) Survey content: length, leaf width, number of leaves, chlorophyll content (SPAD), length of lower branches, fresh weight (aboveground, underground)

[0047] 3) Processing content

[0048] Table 1

[0049]

[0050] 4) Cultivation overview: On December 17, radish seeds were planted at intervals of 30 for cultivation. During the cultivation period, except for the experimental preparation, no other pesticides or fertilizers were used. Use groundwater to infuse the soil with water as needed. The rest are cultivated according to common methods.

[0051] 5) Experimental area distribution: random distribution 3 r...

Abstract

The present invention relates to a method for preparing a plant growth promoter by solid fermentation of chitosan and a method of promoting plant growth using the method. The plant growth promoter according to the present invention is prepared by solid fermentation of chitin using Rhizopusoligosporus strain and has good preservation and plant growth promoting effect. The chitosan useful to a human body may be absorbed into plants.

Description

technical field [0001] The invention relates to a preparation method of a plant growth promoter utilizing chitosan solid fermentation. Background technique [0002] Chitin is a natural polymer material rich in resources, which is only arranged after the cell membrane. Chitin is mainly distributed in crustaceans such as crabs, crayfish, or shrimps or fungi, and higher plant cell walls such as algae. Chitosan is prepared by de-aldohylation of chitin, and the solubility in water is different according to the degree of de-aldohylation. In recent years, chitosan has the advantages of non-toxicity, environmental protection and high biological adaptability, and has been used in many fields. Chitosan activates cells, suppresses aging, strengthens immunity, and prevents diseases. Therefore, it is recognized that it can improve the natural healing ability of organisms and adjust the rhythm of organisms. In addition, it has the functions of adsorbing harmful cholesterol, excreting an...
